Bugzilla seems to execute a default query instead of stored query. I selected a stored query by changing leftmost radio button, then selecting a query, and hitting "Submit" button.
seems to work for me, which stored query are you trying to access?
Please try this again with the newest cut of Bugzilla and reopen if still a problem. http://bugzilla.redhat.com/rh-bugzilla-beta3
Created attachment 81824 [details] URL which beta3 generated
Still broken with beta3. Dunno if that helps, I attached a copy of resulting URL. It's in a file because it's so huge. Observe that it has "zaitcev-assigned" mangled into it, only it does not help. Let me know if you want me to examine browser cookies or something of that nature.
One more thing. If I change the drop-down box right near the radio button from "Run" to "Load", then select "zaitcev-assigned", and hit "Search", Bugzilla loads a query which seems correct. So, it remembers it all right. Searching using what was loaded yields a correct result.
this is probably due to a variable in the URL string actually changed to something different with the newer version. It could be causeing it to crash. A quick fix would be to do a "Load" of failing queries and resave them with same name which will overwrite the old with the new working one. I will have to go through the URL string more carefully to find the differences since this will probably hit some other people too.
